Yes and no. There are services out there that make it easy for restaurants to have a great online presence, including online ordering (here is an example www.getbento.com). And generally I think restaurant websites have been getting better and better. Restaurant owners are much more aware of the importance of online presence.

That's only half the battle though, food delivery marketplaces like Grubhub are very entrenched and changing consumer behavior back to using the restaurant's website takes time and effort. Marketplaces also spend a ton on marketing to make sure consumers go through them and not directly via the restaurant's website. It's an uphill battle for the restaurants.
